CHURN.

.TJPECIPICATION forming part of Letters Patent No, 306,220, dated October 7, 1884.

Application filed March 25, 1884.

To all whon'z, it bury concern:

Be it known that I, JOHN \VJGLARK, of Banksville, Allegheny county, and State of Pennsylvania, have invented a new and Improved Oh urn, of which the following is a full, clear, and exact description.

The invention consists in the construction and combination of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a side View ofmy improved churn, parts being broken out. Fig. 2 is a sectional plan view of the same on the line a; :r, Fig. 1.

The creanrbox A is provided with a cover, '3, on which a hollow or two-legged standard, 0, is held, which is secured detachably on the cover b y two thumb-screws, D, screwed through the bases of the legs of the standard into the said cover.

In the top of the standard 0 a shaft, E, is

j ournaled, on one end of which is rigidly mounted a beveled cog-wheel, F, andon the other end is rigidly mounted a crank, G, provided with a handle, G. The bevel cogwheel F engages with a bevel-pinion, H, mounted rigidly on the upper end of a vertical shaft, J, journaled in the bottom of the box A and in the cover, and on the lower end of which shaft wings K are mounted.

On each side of the shaft J dasher bars or rods L are held to reciprocate vertically, and on the lower end of each dasher-rod a dasher, M, is secured. The dasher bars or rods L are cally opposite the crank.

(No model.)

secured on one side of the box, and its pistonrod Q is connected by a connecting-rod, R, with a lever, S, pivoted in a standard, T, on the cover, the other end of the lever S being connected by a connectingbar, U, with the wrist-pin O. The bottom of the cylinder of the pump 1 is connected with the interior of the box. A wire-netting receptacle, W, for a thermometer is secured on the inner surface of one of the sides of the box directly below the cover. If the shaft E is revolved, the bevel cog-wheel F revolves the pinion H and the shaft J, and the dasher bars or rods L are reciprocated. At the same time the air-pump is operated and cold air is pumped into the cream-box. If the cream is cool enough, the pump can be disconnected, so as not to be operated. If the churn is to be emptied, the on tire working mechanism and the standard 0 carrying it can be disconnected by loosening the screws D.

The dashers M do not move downward sufficiently to interfere with the wings K.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a churn, the combination, with a creambox, of the standard 0, the shaft E, the bevel cog-wheel F, the vertical. shaft J, provided at its top with a bevel-pinion, H, engaging with the bevel cog-wheel 1*, wings K on the lower end of the shaft J, the reciprocating dasher bars or rods L, connected by connecting-bars with the bevel cog-wheel and a crank, (1, the pump P, the pivoted lever S, for working the pump, and of a bar connecting the lever S with the bevel cog-wheel, substantially as herein shown and described.
